* feat(boolean-operations): implement boolean operations in the editor - Added a new BooleanToolbar component for union, subtract, and intersect operations. - Integrated boolean operations into the layer context menu and keyboard shortcuts. - Enhanced the editor layout to include the boolean toolbar for improved user interaction. - Updated internationalization support with new translation keys for boolean operations. - Bumped version to 0.3.0 to reflect the addition of these features. * refactor(editor): update editor layout and panels for improved functionality - Replaced the PropertyPanel with a new RightPanel that includes both Property and Code panels. - Removed the CodePanel from the main editor layout and integrated it into the RightPanel. - Updated keyboard shortcuts to switch the right panel to the code tab. - Enhanced the LayerPanel with a resizable width feature for better user experience. - Added internationalization support for new right panel labels and code panel features. - Introduced new code generation capabilities for various frameworks in the CodePanel. - Improved overall layout structure for better responsiveness and usability. * feat(electron): implement .op file association and enhance file handling - Added support for .op file association in electron-builder, allowing OpenPencil documents to be opened directly from the file system. - Implemented IPC handlers for opening and reading .op files, ensuring proper loading of document content. - Enhanced the main process to handle file opening events on macOS and single-instance locking on Windows/Linux. - Updated the renderer to listen for file open events and load documents accordingly. - Improved README to reflect new file association feature. * fix(canvas): improve layout accuracy for AI-generated designs - Unify lineHeight default via canonical defaultLineHeight() function - Unify text measurement by removing duplicate estimators in generation-utils - Fix optical centering formula to scale proportionally with fontSize - Round layout positions to whole pixels to prevent sub-pixel artifacts - Recursively sanitize nested x/y in streaming layout containers - Fix input trailing icon alignment using fill_container instead of space_between * feat(canvas): right-align agent badge and add breathing glow border - Agent badge now right-aligned to frame's right edge instead of after label - Added breathing glow border around agent-owned frames during generation - Glow border uses same color and lifecycle as the agent badge - Removed unused BADGE_GAP constant and useDocumentStore import * feat(code-panel): enhance tab scrolling functionality and add scrollbar utility - Introduced left and right scroll buttons for tab navigation in the CodePanel, improving user experience for navigating long tab lists. - Added a custom utility to hide scrollbars for a cleaner interface. - Updated styles for better responsiveness and usability in the CodePanel layout. * fix(docs): update Discord invite links in multiple README files - Replaced outdated Discord invite links with the new link across all language-specific README files. - Ensured consistency in the documentation for community engagement. * feat(code-panel): enhance system prompt for responsive design - Updated the ENHANCE_SYSTEM_PROMPT to emphasize the importance of responsive design in code rewriting. - Added detailed guidelines for converting fixed pixel widths to relative units and using responsive Tailwind breakpoints. - Ensured that the output remains visually faithful on desktop while adapting gracefully across screen sizes. * feat(docs): add WeChat group information to README.zh.md and include group image - Introduced a new section in the Chinese README to provide details about the WeChat group for community engagement. - Added an image representing the WeChat group for better visibility and user interaction. * feat(electron): enhance theme management and title bar overlay for Windows/Linux - Updated the `setTheme` method in the Electron API to accept custom colors for the title bar overlay, improving theme synchronization across platforms. - Adjusted title bar overlay colors for Windows and Linux to ensure proper visibility and aesthetics. - Enhanced the top bar component to read computed CSS colors and apply them dynamically, ensuring a consistent user interface. - Improved handling of theme changes in the application to support background and foreground color customization. * fix(screenshot): update screenshot image for improved clarity and quality * fix(docs): update WeChat group image path in README.zh.md for consistency * fix(ai): fix post-generation validation pipeline and text centering - Fix Agent SDK validation: save temp screenshots inside project dir (.openpencil-tmp/) so Claude Code plan mode can read them, instead of /tmp/ which is outside the project sandbox - Enrich validation tree dump with fill colors, stroke, fontSize, fontWeight, textAlign, cornerRadius, opacity for comprehensive visual analysis - Add multi-round validation with quality scoring (threshold 8/10), 500ms stabilization delay between rounds - Add detailed debug logging to applyValidationFixes showing which nodes were found/skipped and property changes - Fix canvas sync needsTextbox check to also account for textAlign (matching isFixedWidthText in factory), preventing IText↔Textbox thrashing on every sync tick - Auto-center text in vertical+center layouts by expanding to full container width and injecting textAlign:'center' - Force Textbox for non-left-aligned text so textAlign is respected (IText ignores width and computes its own) * fix(canvas): use precise text width estimation for fit-content layout Remove the 14% safety factor from text width estimation when computing fit-content/natural-width text dimensions. IText auto-computes its own width and ignores our setting, so the safety margin only inflated the layout allocation, making text appear left-shifted within its container. * fix(canvas): center fit-content text in horizontal layouts For text nodes with fit-content width in horizontal layouts, set textAlign:'center' to compensate for width estimation inaccuracy. The estimated box is typically wider than the actual rendered text, causing left-aligned text to appear visually shifted. Centering distributes the estimation error evenly on both sides. * feat(ai): show validation details in checklist panel - Accumulate validation log (screenshot, analysis, fixes) instead of overwriting status messages, so the full process is visible - Preserve step thinking content in buildFinalStepTags (was discarded) - Add details field to pipeline items and render in checklist UI - Each validation step now shows: screenshot captured, issues found, quality score, fixes applied * feat(ai): add visual reference pipeline types and integration hooks - Add DesignSystem and VisualReference types to ai-types - Add 'visual-ref' mode to AIDesignRequest and SubTask.htmlReference - Detect visual-ref candidates in chat handlers (landing pages, websites) - Wire visual-ref mode in design-generator and orchestrator - Inject HTML reference snippets into sub-agent prompts * feat(ai): add modular design principles for sub-agent context - Add design-principles module with topic files: color, typography, spacing, composition, components - Selectively load relevant principles based on prompt content - Inject design principles into sub-agent system prompts * feat(ai): implement visual reference pipeline - Add design-system-generator: generates color/typography/spacing tokens - Add design-code-generator: generates HTML/CSS from design system - Add html-renderer: renders HTML to screenshot via html2canvas - Add visual-ref-orchestrator: coordinates the full pipeline (design system → HTML code → screenshot → enrich subtasks) - Add html2canvas dependency for client-side HTML rendering * feat(mcp): default filePath to live canvas and fix cross-platform issues - Default all MCP tool filePath to live://canvas when omitted, so tools operate on the real-time canvas instead of stale files - Remove filePath from required params in all tool schemas (21 interfaces) - Fix mcp-server-manager.ts using process.cwd() which fails in Electron production on Linux — now checks ELECTRON_RESOURCES_PATH first - Fix stopMcpHttpServer using SIGTERM on Windows — use taskkill instead - Force new children reference in applyExternalDocument to ensure canvas sync subscriber always detects MCP-pushed document updates * feat(mcp): enhance design prompt with semantic roles, CJK typography, and layout rules Add comprehensive design knowledge to MCP design prompt for better AI-generated designs: design type detection (mobile vs desktop), full semantic role reference with context-aware defaults, CJK typography rules, expanded text/layout/form guidelines, and detailed post-processing documentation. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat(ai): implement intent classification for chat handlers - Replace hardcoded keyword matching with a lightweight LLM call to classify user intent in chat messages. - Introduce a new function `classifyIntent` to determine if the request is for design generation or conversation. - Update design request handling in `useChatHandlers` to utilize the new classification method. - Enhance design prompt documentation to reflect changes in design type detection based on intent rather than keywords. * fix(ai): handle string qualityScore in validation response parsing The LLM sometimes returns qualityScore as a string (e.g. "8" instead of 8), causing it to fall through to 0. Also hide misleading "quality: 0/10" display when the score couldn't be determined, and log raw response for debugging. * fix(ai): increase validation timeout to 90s and fix quality score parsing Agent SDK validation requires spawning a process, reading the image, and analyzing it — 30s was consistently timing out. Also handle string qualityScore values from LLM responses and hide misleading 0/10 display. * fix(ai): fix validation timeout and response parsing - Increase validation timeout from 30s to 180s (Agent SDK needs time for subprocess spawn + OAuth auth + multi-turn image reading) - Strip <tool_use> XML blocks from Agent SDK response before extracting JSON — the tool call XML was confusing the regex, causing qualityScore to parse as 0 despite valid JSON being present - Handle string qualityScore values and hide misleading "quality: 0/10" - Revert unnecessary direct API key approach for validation * fix(ai): prevent node ID collisions between generations When generating new content on a canvas with existing nodes, AI-generated IDs (e.g. brand-spacer) would collide with previous generations. Now captures pre-existing node IDs at generation start and checks against them during upsert sanitization. Remapped IDs are tracked in generationRemappedIds so progressive streaming updates can still find their nodes. * fix(ai): require styleGuide in orchestrator plan and fix validation detail icons - Add fallback default styleGuide when orchestrator LLM omits it - Strengthen prompt to mark styleGuide as REQUIRED - Replace emoji icons in validation details with [done]/[pending]/[error] markers for consistent styling with the checklist design system * feat(server): add port file plugin for server instance discovery - Introduce a new Nitro plugin that writes a port file on server startup to allow the MCP server to discover the running instance, whether it's a development server or Electron. - Implement error handling in the Electron main process for writing the port file, logging any failures. - Update Vite configuration to include additional external dependencies in the rollup configuration. * feat(electron): implement IPC for retrieving pending file paths - Added a new IPC handler `file:getPending` to retrieve and clear the pending file path when the React app mounts. - Updated the Electron API to include `getPendingFile` for renderer access. - Enhanced the `useElectronMenu` hook to load any pending file on application startup. - Updated UI components to reflect changes in file handling and improved user experience. * fix(panels): replace emoji icons with styled icons in validation checklist - Parse [done]/[pending]/[error] prefixes in detail lines and render as styled circle icons matching the parent checklist design system - Replace remaining emoji markers in design-validation.ts with text prefixes - Fix isApplied detection to recognize new [done] Applied marker * refactor(electron): update settings path to use platform-standard app data directory - Changed the settings file path to utilize Electron's user data directory for better cross-platform compatibility. - Updated the settings writing function to ensure the user data directory is created if it doesn't exist. - Added comments to clarify the storage location for different operating systems. - Implemented a fixed partition for localStorage/cookies to maintain data across server port changes. * feat(ai): enhance validation with pre-checks, structural fixes, and border detection - Add design-pre-validation.ts: pure code checks before LLM validation - Invisible container detection (same fill as parent → auto-add border) - Sibling consistency (majority-rule for height/cornerRadius) - Add structural fixes to validation: addChild/removeNode operations - Icon injection via lookupIconByName with server fallback - autoFixParentLayout with child count guard to prevent layout breakage - Add strokeColor/strokeWidth to safe fix properties for border fixes - Simplify intent classification: all design requests use visual-ref pipeline - Fix checklist: "Found N issues" now shows [done] instead of [pending] - Fix qualityScore: only update when > 0 to preserve valid round scores * fix(ai): cherry-pick safe validation improvements, drop aggressive pre-checks Keep: stroke tree dump bug fix (object not array), qualityScore=0 false positive detection, fit_content→fixed safety guard, empty path removal, type-specific sibling consistency, repeated fix filtering, screenshot extraction to design-screenshot.ts. Drop: detectForcedFixedHeight (destroyed input/button heights), MAX_VALIDATION_ROUNDS 5 (too many rounds), removal of quality threshold early stop, section regeneration phase. --------- Co-authored-by: Fini <fini.yang@gmail.com> Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
